When running a script using nohup piping your output to a log you may receive this message “nohup: ignoring input and appending output to `nohup.out'”. This is just a notice to tell you that standard error message will also be sent to standard out which is being redirect to a log file. This is nothing to worry about but if you would prefer not to have the message printed you can tell nohup that you want both stderr and stdout to go to the same file very easily. This is ideal for scripts run in cron or schedule to avoid unnecessary log messages.
Example of message when running a script
nohup $DOMAIN_HOME/startWebLogic.sh > ~/logs/start_$1_domain.`date +%y%m%d%H%M%S`.log &
nohup: ignoring input and appending output to `nohup.out'
Do the following to avoid this message.
nohup $DOMAIN_HOME/startWebLogic.sh > ~/logs/start_$1_domain.`date +%y%m%d%H%M%S`.log 2>&1 &
